ABSTRACT
MDARS is a Semi-autonomous unmanned ground vehicle with intrusion detection & assessment, product & barrier
assessment payloads. Its functions include surveillance, security, early warning, incident first response and product and
barrier status primarily focused on a depot/munitions security mission at structured/semi-structured facilities. MDARS
is in Systems Development and Demonstration (SDD) under the Product Manager for Force Protection Systems (PM-
FPS). MDARS capabilities include semi-autonomous navigation, obstacle avoidance, motion detection, day and night
imagers, radio frequency tag inventory/barrier assessment and audio challenge and response. Four SDD MDARS Patrol
Vehicles have been undergoing operational evaluation at Hawthorne Army Depot, NV (HWAD) since October 2004.
Hawthorne personnel were trained to administer, operate and maintain the system in accordance with the US Army
Military Police School (USAMPS) Concept of Employment and the PM-FPS MDARS Integrated Logistic Support
Plan. The system was subjected to intensive periods of evaluation under the guidance and control of the Army Test and
Evaluation Center (ATEC) and PM-FPS. Significantly, in terms of User acceptance, the system has been under the
“operational control” of the installation performing security and force protection missions in support of daily operations.
This evaluation is intended to assess MDARS operational effectiveness in an operational environment. Initial
observations show that MDARS provides enhanced force protection, can potentially reduce manpower requirements by
conducting routine tasks within its design capabilities and reduces Soldier exposure in the initial response to emerging
incidents and situations. Success of the MDARS program has been instrumental in the design and development of two
additional robotic force protection programs. The first was the USAF Force Protection Battle Lab sponsored Remote
Detection Challenge & Response (REDCAR) concept demonstration executed by the Air Force Robotics Lab (AFRL).
The REDCAR used an MDARS PUV as the central robotic technology and expanded the concept to incorporate a
smaller high speed platform (SCOUT) equipped with lethal, non-lethal and challenge components as an engagement
platform and, in a marsupial configuration on the MDARS, a small UGV that can be deployed to investigate close
quarters areas. The Family of Integrated Rapid Response Equipment (FIRRE) program further expands these concepts
by incorporating and adapting other mobile/tactical force protection equipment with a more robust Unmanned Ground
Vehicle into an “Expeditionary” configuration to provide the current force with a rapidly deployable force protection
system that can operate in austere less structured and protected environments. A USAMPS/ MANCEN sponsored
“FIRRE System Demonstration” in Iraq is scheduled to begin in FY ’07.

THE BACKGROUND:

The Mobile Detection Assessment Response System (MDARS) provides Continental US (CONUS)
installation commanders an electro-mechanical capability to conduct semi-autonomous random patrols and surveillance
activities to include barrier assessment and theft detection functions. The MDARS can be used in a variety of military
installations (i.e., depots, storage areas for rail, air, and port facilities, and Arms, Ammunition and Explosives (AA&E)
storage facilities) to detect unauthorized access to a facility; verify the status of barriers and products; and investigate
the source of alarms from remote locations before dispatching armed guards to the scene. Current Intrusion Detection
System (IDS) technology requires manual assessment and response to alarms that could expose personnel to life
threatening situations. MDARS provides commanders with an enhanced capability to counter covert and overt threats,
reduce risk to personnel, and reduce manpower requirements used for security and inventory functions.

An Operational and Organizational Plan for a robotic security system was approved in March 1985. The
concept formulation package was completed in May 1991 and showed MDARS to be the best approach for satisfying
the mission need for both an interior and exterior systems. In 1992, the Secretary of the Army for Research,
Development and Acquisition issued a memorandum directing the MDARS program development using Office of the
Under Secretary of Defense funds with the U.S. Army Materiel Command as principal proponent which approved a
Requirements Document in June 1993. In February 1994, the Defense Logistics Agency also issued a Mission Need
Statement for MDARS capability. The U.S. Army Training and Doctrine Command (TRADOC) approved the MDARS
Operational Requirements Document (ORD) in May 1996. A Broad Agency Announcement contract was awarded
Robotic Systems Technology of Westminster, MD in September 1993. This effort culminated in the Technical
Feasibility Test (TFT) of a prototype MDARS-Exterior (MDARS-E) conducted in May 2000 at Aberdeen Proving
Grounds, MD. (See Figure 1) With the TFT results, an updated MDARS ORD was prepared and submitted in support
of a Milestone I/II for the MDARS-E. (Approved in December 2004)

Figure 1: The MDARS-E Prototype Vehicle during TFT May 2000 at APG, MD

The successful Milestone decision approved moving the MDARS program into the System Design and
Development (SDD) phase of the acquisition program. And, following that event, a four year SDD contract was
awarded in 2002 to General Dynamics Robotic Systems (GDRS), formerly RST. The MDARS program uses an
evolutionary acquisition strategy and spiral development approach for development. Technology readiness and
funding for robotics necessitates this methodology. The Capabilities Production Document (CPD) is a conversion
from an ORD to a CPD in support of a Milestone C, scheduled for December 2006, in accordance with the DoD 5000
series and Chairman Of Joint Chiefs of Staff Manual and Instructions, and provides the attributes (Threshold and
2
Objective) for the MDARS Increment-1. The CPD was formulated after the MDARS final SDD critical design
readiness review. Tradeoff decisions have been made and a more precise determination of the performance parameters
is incorporated. Initial fielding of the system begins in Fiscal Year (FY) 08 and continues until all systems required by
the Office of the Provost Marshal General have been delivered.

FY2004 was a significant test year for the MDARS. Effort was initiated in testing both software and
hardware. SPAWAR completed several iterations of software regression testing and GDRS completed Product
Qualification Testing 1a at their facility. All test activity was conducted under the watchful eye of Army Test Center
personnel. In addition, and following the selection of Hawthorne Army Depot, NV as the system operational
assessment facility, GDRS was directed to conduct a survey of the facility in preparation for the installation of the
MDARS and identify facility preparation required to support the system. This was accomplished, infrastructure was
upgraded as needed and the system installation was initiated in the 4th Quarter of 2004.

In FY 2005, three major and significant activities were accomplished in the MDARS program. The first was a
modeling and simulation effort placing the MDARS in a tactical environment was conducted with favorable results.
This effort expanded on the MDARS capability to be a semi-autonomous, unmanned patrol vehicle in a structured /
semi-structured environment, to operations outside a defined perimeter on semi to unstructured terrain in support of
force protection/physical security missions in a more hostile environment. As a result, a concept has been initiated,
known as the Family of Integrated Rapid Response Equipment (FIRRE), to integrate force protection sensors with
robotic response equipment into a self supporting rapid response mission set and is currently undergoing the Joint
Capabilities Integration and Development System analysis. It is anticipated that a series of FIRRE technology
demonstrations, both CONUS and OCONUS, will be conducted in FY 06-07.

The second major event was the conduct of a 30 day Early User Appraisal (EUA) of the MDARS in the 3rd
Quarter of FY 2005 at Hawthorne Army Depot, NV, an operational arms, ammunition and explosives storage area.
Hawthorne personnel were trained to perform all System Administration, Operator, organizational maintenance and
preventive maintenance checks & services tasks and functions. The EUA was an intense 30 days of a variety of
exercises and scenario situations intended to identify system strengths and weaknesses.

The third event was the completion of a year long system assessment in that same environment. This is the
focus of this paper.

THE OPERATIONAL CONCEPT:

The MDARS system consists of robotic platforms capable of preprogrammed autonomous movement, motion detection,
barrier, product, incident assessment subsystems, two way communications capability, and in the future when supported
by policy, may employ a non-lethal response to be added in the modernization phase following Milestone C. It will be
capable of operating in a stand-alone mode or in conjunction with existing Intrusion Detection Systems (IDS). The full
operating system will consist of pair(s) of mobile platforms employing a suite of sensors that are preprogrammed or
remotely controlled by an operator located at a remote monitoring and control point. The MDARS will provide
commanders a means of conducting semi or fully autonomous random patrols in operational security environments.
The MDARS monitor point may be co-located with and operated by existing IDS or Integrated Commercial Intrusion
Detection System (ICIDS) monitor point personnel. The MDARS monitor point will have continuous operational
control of the system, and can make automatic digitized records of all operations including the capability to record and
store video images. MDARS will rely on a radio communication network to ensure continuous two-way communication
to include repeaters/relays, possibly fiber optic cabling, laser, or microwave communication technologies. MDARS
shall be programmable for a variety of functions or mission profiles. During installation, MDARS will be configured or
customized for each designated facility/area and the security mission profiles required of that facility. At a minimum
this programming will include: the terrain to be patrolled, its boundaries, designated “way points,” operational checks to
3
be performed, and any specialized response or assessment features programmed into the system during the installation
process. MDARS shall be capable of conducting 24 hours a day, 7 days a week operations in most environmental
conditions.

MDARS shall be programmable for a variety of functions. During installation, MDARS will be configured or
customized for each designated facility/area and mission(s). At a minimum, the terrain to be patrolled and its
boundaries, designated “way points”, operational/security checks to be performed, and any specialized features or
payload packages will be programmed into the system. MDARS shall be capable of conducting continuous operations.
The MDARS will operate within a defined area of operation or an enclosed security area, preferably with limited traffic
in the security area during MDARS operations. The routine exception will be other security vehicles. MDARS will
operate primarily on the road network within the area, with some off-road capability for short-term operations. The
MDARS will be programmed and equipped for its operational area and missions. The MDARS will be smaller than a
compact automobile, able to operate within a single lane, and, in order to operate in most environmental conditions, will
have robust mobility system and sub-systems designed for exterior use. A high level Operational Concept graphic is
shown as Figure 2.

Figure 2. High Level Operational Concept

THE SYSTEM:

MDARS consists of an MDARS Control Station (MCS) and pairs of remote vehicles (patrol units) each
equipped with a Mission Payload Suite (MPS). The following descriptions of the systems key features are based on the
System Development and Deployment (SDD) system engineering models (pre-production prototypes). Production units
are expected to be similar.

(1) The MCS is a distributed processing system that coordinates the operation of multiple semi-
autonomous patrol units. The MCS uses the Government-developed (Navy SPAWAR Systems Center, San Diego, CA)
Multiple Resource Host Architecture (MRHA) as its application software. The system is designed to run automatically
with only minimal human intervention. The MCS provides the user with overall situation awareness and the ability to
execute preplanned patrols, random patrols, or user-directed patrols. The MRHA application software (GFE) is a
distributed, LAN-based, multi-processing system that can be expanded to accommodate up to 32 platforms. The heart
of the system, referred to as the "Supervisor," is a Windows NT based computer with a high-resolution display. The
Supervisor represents the highest level in the control hierarchy, both from a distributed computational resource as well
as a user interface perspective. A window on the Operator Station displays the remote video image being transmitted
from the vehicle. The Supervisor will maintain a ready representation of the "big picture" and will schedule and
coordinate the actions of the various Patrol Unit Vehicles (PUV) and display appropriate status and location information
to the guard. The Supervisor has at its disposal a number of Planner computers linked over a common high-speed LAN.
4
The Planner performs virtual path and unrestricted path planning functions on an as needed basis. The Supervisor has
access to one or more Operator Stations also linked over the LAN. These Operator Stations consist of individual
console input/output stations with Video Graphics Adapter (VGA)-display capability that can be assigned to a particular
platform when close attention by a guard is required. This allows the Supervisor to allocate both computational
resources and human resources to address the various situations that may arise in the control of remote vehicles.
The graphic at figure 3 shows the major elements/ subsystems that make up the MDARS system and how
they fit together.

Figure 3. MDARS System Interface Description

The MDARS, by design for this increment, operates as a stand-alone security system with single pair to multiple
pairs of robotic platforms. The primary system that MDARS will support is the installation IDS (or the Army fielded
ICIDS) by operating in the same area without interference or degradation of either IDS or MDARS. The installation
IDS is a fixed point security system with intrusion detection, reporting and, maybe, some fixed camera assessment
systems whereas MDARS is an area security system with mobility, assessment, reporting and response. Supplemental
payload packages on the MDARS may include additional functional capabilities which will also operate without
interference or degradation of basic MDARS function or the installation IDS.
MDARS Increment-1 will be used as non-tactical fixed-site physical security equipment of a low density, contractor
supported equipment for limited deployment to Table of Distribution and Allowances (TDA) unit installations. These
installations will have IDS or ICIDS as their primary electronic physical security system. MDARS, by design, will be
able to carry supplemental payload packages. There are two such packages being developed to operate from the
MDARS robotic platform. The Barrier Assessment System (BAS) and a Product Assessment System (PAS) are being
co-developed from operational application with MDARS. The BAS can electronically check an electronic lock system
via a radio frequency inquiry and response. The PAS uses Radio Frequency Identification (RFID) tags on products with
the ability of the MDARS to make an inquiry and report its status. Both systems co-exist on the MDARS as
supplemental payload packages, using power and communications assets of MDARS to function in a timely manner. A
system depiction incorporating these additional components and capabilities is provided as Figure 4.

Figure 4. MDARS Increment 1 System Components

(2) The patrol unit has onboard navigation subsystem, communications subsystem, obstacle avoidance
subsystem, and a MPS consisting of intrusion detection and assessment system with supplemental payload packages of
barrier assessment (BAS) and product assessment (PAS) systems. The actual number of patrol units included in a given
system will be site specific. The PAS consists of an interrogator mounted on the PUV, a database linked to the MCS,
and a number of Radio Frequency (RF) activated tags. The tags are affixed to items of equipment or products within
the patrol area. The PAS interrogator will query the tags and read any stored data. Product database reports include
information on expected and calculated tag location, missing tags, misplaced tags, and unexpected tags found. The
BAS consists of an interrogator mounted on the PUV, a database linked into the MCS, and a lock mechanism equipped
with a sensor and RF transceiver. The locks are installed on storage igloos and buildings. As the PUV conducts patrols,
the BAS interrogator reads the lock status. Status is defined as “open,” “closed,” or “error.” The BAS provides an
immediate indication that a bunker or building lock has been tampered with or compromised. See Figure 5.

Figure 5. PUV Components.

(3) The Associated Support Items of Equipment consists of Communications Relays/Repeaters, Navigational
Aids, Remote Area resources, and differential Global Positioning System. These devices extend the distances between
the PUV and the MCS, provide for navigation through the patrol area by the patrol unit, and are the components for
indicating functionality at the BAS locations.

THE OPERATIONAL ASSESSMENT:

In October 2005, the MDARS completed a successful, year long Operations Assessment and Early User Appraisal (EUA)
period at Hawthorne Army Depot (HWAD) in Nevada, the largest Army munitions storage depot in the world. MDARS, a joint
Army-Navy development effort to provide automated robotic intrusion detection, response and inventory/barrier assessment
capability for use on DoD facilities, is managed by the US Army Office of the Product Manager, Force Protection Systems (PM-
FPS). The Multiple Resource Host Architecture (MRHA) command-and-control software was developed by SSC San Diego, while the
unmanned patrol unit vehicle (PUV) was developed by General Dynamics Robotic Systems (GDRS). The MDARS system deployed
to Hawthorne in early FY2005, consisted of four PUVs, the command-and-control console/software, and communications equipment.
In addition, other associated items of equipment including the newest Navy high security Internal Locking Device(ILD), store
forward communications and RFID tags and readers were installed on selected storage structures. (See Figures 6 through 10)

Selected site personnel between 40 and 64 hours of training and were certified to perform a number of MDARS functions.
These functions included system operations, system administration, system maintenance and pre and post patrol Preventive
Maintenance Checks and Services (PMCS) on the PUV’s. (See Figures 12 through 15) During the year-long effort, which concluded
in October 2005, the autonomous PUVs patrolled assigned portions of the depot (about 30 square miles, See Figure 11) for 12 hours
per day on weekdays (Monday – Thursday) and 24 hours per day on weekends (Friday – Sunday). Their normal routine mission
taskings included intruder detection sentry stops at designated programmed nodes around the patrol area perimeter and at selected
points along the patrol paths, monitoring and reporting the status of the high-security ILD’s on munitions bunkers, and tracking the
presence/location of tagged munitions using active RFID technology.

The MDARS command and control console, located in the Guard Operations Center (GOC) was operated by Hawthorne
personnel who operated the system as an additional task along with their normal functions of guard operations communications and
IDS monitors. During this period, and particularly during the EUA, representatives of the program office introduced selected events
(such as intruders, blocked paths, opened locks, and moved containers) to observe not only how both the system and users would
respond, but also to observe whether or not the system control was user friendly. In all, over 100 exercise scenarios were introduced
over the period. A further objective to identify other contributions that the MDARS could make in emergency situations such as fires,
hazardous materials accidents, communications outages, fixed IDS failures, etc. was also addressed. Most efforts in this regard were
successful, but depended greatly on the level of comfort and expertise developed by the Operator. Over the course of the system
assessment, the four robots patrolled in excess of 2000 hours and traveled over 16,000 kilometers (10,000 miles). Most system
operators became very comfortable and competent with normal operation, and acquired varying levels of proficiency in responding to
exceptional events such as intruders and open locks and manual control of the PUVs. As an example, driving the PUV between a
storage structure headwall and the protective blast barrier, a width of 14 feet, was difficult because of the PUV obstacle avoidance
parameters, but it was a driving task that could be accomplished by an operator comfortable with the knowledge that the PUV would
not collide with the obstacles it sensed and who could stay with the effort in spite of the close quarters. Automated product tracking
using RFID tags was found to be highly reliable, giving near-real-time notification of inventory discrepancies. Most importantly, both
robot and MRHA developers gained valuable real-world data on hardware and software performance, as well as potential areas for
improvement and the “Users” of the system were able provide valuable input on both hardware and software interface in a real world
operational environment.
